Ruby on Rails (also known as RoR or simply Rails) is an object-oriented, multi-level, full-stack framework running via Ruby’s programming language. Many web developers choose to work in Ruby on Rails due to its numerous advantages. Why do developers love RoR? The best-known advantage of Ruby on Rails web development is the speed. A variety of handy instruments and Ruby’s support on the Rails community increase development speed by about 30-40%. With Ruby on Rails, you get excellent built-in testing, caching, localization, validation, and deployment tools. And that’s not it. You also get an opportunity to customize the routing and titles of the website sections so that your projects always have simple and beautiful URLs. The database migration process is perfect in Rails. The database structure always stays in the repository, and every change in structure gets instantly documented.
